MC74AC245数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The MC74AC245/74ACT245 contains eight non-inverting bidirectional bufferswith 3-state outputs and is intended for bus-oriented applications. Current sinkingcapability is 24 mA at both the A and B ports. The Transmit/Receive (T/Rbar) inputdetermines the direction of data flow through the bidirectional transceiver. Transmit(active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enablesdata from B ports to A ports. The Output Enable input, when HIGH, disables both Aand B ports by placing them in a High Z condition.

特性 Features

• Noninverting Buffers
• Bidirectional Data Path
• A and B Outputs Source/Sink 24 mA
• ACT245 Has TTL Compatible Inputs
• Pb-Free Packages are Available

简介

MC74AC245属于集成电路（IC）的缓冲器驱动器接收器收发器。由制造生产的MC74AC245缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。
